Differences of Socio-psychology, Eating Behavior, Diet Quality and Quality of Life in South Korean Women according to Their Weight Status

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.

Evaluation of Diet Quality of Children and Adolescents Based on Nutrient and Food Group Intake and Diet Quality Index-International (DQI-I) / 대한지역사회영양학회지

It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.

The Effect of Repeated Nutrition Education on Health Improvement Program by Diet Quality Index-International (DQI-I) Evaluation in Office Workers / 대한지역사회영양학회지

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month follow-up. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.
